Measures to save water in commercial use

PUB, the national water agency, thanks Mr Thomas Lee Chee Chee ("Supply non-potable water to more users"; last Saturday) and Mr Paul Chan Poh Hoi ("Dual distribution systems for water needed"; Forum Online, Tuesday) for their feedback.

Newater is supplied through a separate piping system to non-domestic users such as wafer fabrication parks, refineries, hotels, shopping centres and commercial buildings for use in industrial processes, air-con cooling and so on. Suntec City and Raffles City are two such premises already using Newater.

With the dry weather expected to continue, PUB has been engaging the non-domestic sector to adopt measures to cut down non-essential water usage such as vehicle washing and irrigation, and switching off water features.

PUB has a range of schemes to encourage companies to increase water efficiency and water recycling for non-potable use. Using seawater for cooling is one such solution and PUB is working with large water users to expand its use. Water recycling for non- potable use is another solution that PUB encourages industries to adopt.

From June next year, PUB will also require large non-domestic water users to develop and submit Water Efficiency Management Plans annually.

This will help companies better analyse their water use, identify potential water savings and implement measures to improve the efficiency of their water use.
